DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following, the solutions according to the embodiments of the present disclosure will be described clearly and completely with reference to the figures, such that the solutions can be better understood by those skilled in the art. Obviously, the embodiments described below are only some, rather than all, of the embodiments of the present disclosure. All other embodiments that can be obtained by those skilled in the art based on the embodiments described in the present disclosure without any inventive efforts are to be encompassed by the scope of the present disclosure.

A vehicle for carrying a container is provided according to embodiments of the present disclosure. A locking mechanism of the vehicle may switch between a locked state and an unlocked state under control of a microcontroller unit. When the above vehicle is used for carrying or transportation of a container, the processes for locking and unlocking the container may be simplified i.e., the locking and unlocking of the container may be automated. Accordingly, the vehicle is advantageous in that it is capable of locking and unlocking the container in a simple way, thereby improving the efficiency of the vehicle in transportation of the container. The above vehicle may be an unmanned vehicle, an ordinary truck driven by a driver, or a rail vehicle carrying a container.

Here, referring to FIGS. 1, 2 and 3, a vehicle 1 for carrying a container is provided according to some embodiments of the present disclosure. The vehicle 1 includes a vehicle body 11 on which a container is placed. The vehicle body 11 as shown in FIG. 1 has a flat-plate structure. Alternatively, the vehicle body 11 may have surrounding sideboards, or have a structure matching a specific container. The structure of the vehicle body 11 is not limited to the one shown in FIG. 1.

The above vehicle 1 further includes at least one locking mechanism 12 provided on the vehicle body 11 and a microcontroller unit 13 communicatively connected to each of the at least one locking mechanism 12. As shown in the structure of FIG. 1, one locking mechanism 12 is provided at each of four corners of the vehicle body 11. Each of the four locking mechanisms 12 is communicatively connected to the microcontroller unit 13, such that the microcontroller unit 13 may control the locking mechanisms 12. In order to lock the container to the vehicle body 11 reliably, one, two, three, four or more locking mechanisms 12 may be provided on the vehicle body 11 (the present disclosure is not limited to four locking mechanisms provided in the structure shown in FIG. 1). When a plurality of locking mechanisms 12 is provided, their respective positions and arrangement may be configured flexibly. The Microcontroller Unit (MCU) is also referred to as Single Chip Microcomputer or Single Chip Machine.

The microcontroller unit 13 is configured to control each locking mechanism 12 to switch between a locked state and an unlocked state.

Here, each locking mechanism 12 is connected fixedly to the container when the locking mechanism 12 is in the locked state, such that the container is fixed to the vehicle body 11.

When each locking mechanism 12 is in the unlocked state, the container, when having an external force acting thereon, is movable with respect to the vehicle body 11.

For the vehicle 1 according to the embodiments of the present disclosure to carry a container, hoisting equipment such as a crane places the container on the vehicle body 11, with each locking mechanism 12 aligned with a lock hole provided on the container. The microcontroller unit 13 controls each locking mechanism 12 to switch from the unlocked state to the locked state, such that the locking mechanisms 12 may lock the container to the vehicle body 11, i.e., the container is fixed to the vehicle body 11. In order to offload the container from the vehicle body 11, first the microcontroller unit 13 may control each locking mechanism 12 to switch from the locked state to the unlocked state, and then hoisting equipment such as a crane may hoist the container away from the vehicle body 11, thereby completing transportation of the container.

Under control of the microcontroller unit 13, the locking mechanisms 12 of the vehicle 1 may lock and unlock the container placed on the vehicle body 11. Thus, when the above vehicle 11 is used for carrying or transportation of the container, the processes for locking and unlocking the container may be simplified by cooperation of the microcontroller unit 13 and the locking mechanisms 12. Thus, the locking and unlocking of the container may be automated, such that the time required for locking the container to the vehicle body 11 and unlocking the container from the vehicle body 11 may be shortened. That is, the efficiency in locking/unlocking the container to/from the vehicle body 11 may be improved and the time required for loading/offloading the container to/from the above vehicle 1 may be shortened.

To summarize, the vehicle 1 is advantageous in that it is capable of locking and unlocking the container in a simple way, thereby improving the efficiency of the vehicle 1 in transportation of the container.

In a particular implementation, as shown in the structure of FIG. 1, the above vehicle 1 may further include a pressure detection mechanism 14 provided on the vehicle body 11 and communicatively connected to the microcontroller unit 13. As shown in the structure of FIG. 1, a pressure detection mechanism 14 is provided at a central position of the vehicle body 11. One, two, three or more pressure detection mechanisms 14 may be provided on the vehicle body 11.

The pressure detection mechanism 14 may be any detection mechanism capable of detecting a pressure, such as a pressure sensor, a gravity sensor or a weight sensor. In particular, the pressure sensor may be a piezoelectric pressure sensor, a piezoresistive pressure sensor, a sapphire pressure sensor or the like, and the weight sensor may be a photoelectric weight sensor, a capacitive weight sensor, a hydraulic weight sensor, a vibration weight sensor, a gyro weight sensor or the like.

The pressure detection mechanism 14 is configured to detect a value of a pressure applied by the container on the vehicle body 11 and input a signal indicating the detected value of the pressure to the microcontroller unit 13.

When the value of the pressure as detected by the pressure detection mechanism 14 is larger than a predetermined value, the microcontroller unit 13 controls the locking mechanisms 12 to act to switch from the unlocked state to the locked state.

As shown in the structures of FIGS. 1 and 2, when the container is being hoisted by hoisting equipment, such as a crane, to approach the vehicle body 11 or onto the vehicle body 11, the weight of the container is applied to the pressure detection mechanism 14. The pressure applied by the container may be detected by the pressure detection mechanism 14, which inputs the signal indicating the detected value of the pressure to the microcontroller unit 13. The microcontroller unit 13 controls the locking mechanisms 12 to act based on the received signal indicating the value of the pressure. When the received value of the pressure is larger than the predetermined value, indicating that the container is in place, the microcontroller unit 13 controls the locking mechanisms 12 to enter the locked state, such that the locking mechanisms 12 may fix the container to the vehicle body 11, in order for the vehicle 1 to carry the container.

With the above vehicle 1, the pressure detection mechanism 14 may detect the pressure signal for the container, and then the microcontroller unit 13 may determine whether the container is on the vehicle body 11 by comparing the value of the pressure with the predetermined value, thereby achieving automatic control of the locking mechanisms 12. In this way, both manpower and time may be saved and the operating efficiency of the vehicle 1 may be improved.

In particular, as shown in the structures of FIGS. 3 and 4, each locking mechanism 12 may include a housing 121 mounted to the vehicle body 11, a lock 122 protruding from a top of the housing 121, a lock lever 123 connected fixedly to the lock 122 and mounted to the housing 121 in such a manner that the lock lever 123 is rotatable about its axis, and a driving component 124 for driving the lock lever 123 to rotate. As shown in the structure of FIG. 3, each locking mechanism 12 may further include a transmission component 125 connected transmissively to the driving component 124. The driving component 124 may drive the lock lever 123 to rotate clockwise or counter-clockwise via the transmission component 125. Alternatively, the driving component 124 may directly drive the lock lever 123 to rotate. As shown in the structure of FIG. 5, in this case the locking mechanism 12 is in the unlocked state. When the lock lever 123 rotates clockwise or counter-clockwise as driven by the driving component 124, i.e., when the lock 122 rotates from the position shown in FIG. 5 to the position shown in FIG. 6, the locking mechanism 12 switches from the unlocked state to the locked state.

The driving component 124 is communicatively connected to the microcontroller unit 13 and configured to act based on an output signal received from the microcontroller unit 13 to drive the lock lever 123 to rotate by a predetermined angle such that the lock 122 may lock and unlock the container. As shown in the structures of FIGS. 5 and 6, the predetermined angle may be 90° or 270°. Alternatively, it may be set as any angle, not limited to 90° or 270°, depending on actual situations.

With the above vehicle 1, the microcontroller unit 13 may control the driving component 124 to allow the lock lever 123 of the locking mechanism 12 to rotate with the lock 122, so as to achieve automatic locking and unlocking of the container and, in turn, automated locking/unlocking of the container to/from the vehicle 1. This facilitates unmanned operation and automated loading/offloading of a container to/from an unmanned vehicle carrying the container.

In order to improve the accuracy of the automated operations of the vehicle 1, as shown in the structures of FIGS. 3 and 4, the locking mechanism 12 may further include a first photoelectric switch 127 and a second photoelectric switch 128 each mounted to the housing 121, and a block sheet 129 mounted to the lock lever 123. Each of the first photoelectric switch 127 and the second photoelectric switch 128 is communicatively connected to the microcontroller unit 13 and configured to input a switching signal to the microcontroller unit 13. In practice, they may be configured depending on actual situations. For example, in FIG. 4, the locking mechanism 12 may be in the unlocked state when the block sheet 129 is at a position corresponding to the second photoelectric switch 128, or in the locked state when the block sheet 129 is at a position corresponding to the first photoelectric switch 127.

When the microcontroller unit 13 controls the locking mechanism 12 to switch from the unlocked state to the locked state, the driving component 124 drives the lock lever 123 to rotate by a predetermined angle in a first direction, such that the block sheet 129 is at a position corresponding to the first photoelectric switch 127 and the first photoelectric switch 127 transmits a locking signal to the microcontroller unit 13. Here, the first direction may be a clockwise direction or a counter-clockwise direction.

When the microcontroller unit 13 controls the locking mechanism 12 to switch from the locked state to the unlocked state, the driving component 124 drives the lock lever 123 to rotate by a predetermined angle in a second direction opposite to the first direction, such that the block sheet 129 is at a position corresponding to the second photoelectric switch 128 and the second photoelectric switch 128 transmits an unlocking signal to the microcontroller unit 13. The second direction may be a counter-clockwise direction or a clockwise direction, corresponding to the above first direction.

With the above vehicle 1, the locking mechanism 12 is provided with the first photoelectric switch 127 and the second photoelectric switch 128, as well as the block sheet 129 provided on the lock lever 123. Thus, when the driving component 124 drives the lock lever 123 to rotate, the block sheet 129 rotates with the lock lever 123. When the block sheet 129 rotates to the position corresponding to the first photoelectric switch 127, the block sheet 129 blocks the first photoelectric switch 127, such that the first photoelectric switch 127 generates an electrical signal and transmits the locking signal to the microcontroller unit 13. As shown in the structure of FIG. 3, the lock 122 rotates to a locked position. When the block sheet 129 rotates, as driven by the driving component 124, to the position corresponding to the second photoelectric switch 128, it blocks the second photoelectric switch 128, such that the second photoelectric switch 128 generates an electrical signal and transmits the unlocking signal to the microcontroller unit 13. As shown in the structure of FIG. 4, the lock 122 rotates exactly to an unlocked position. With the locking signal or unlocking signal generated by the first photoelectric switch 127, the second photoelectric switch 128 and the block sheet 129, the state of the locking mechanism 12 may be further determined, such that the microcontroller unit 13 may control the locking mechanism 12 accurately, and in turn control the vehicle 1 more accurately, thereby avoiding faulty operations.

In order to increase the driving torque, as shown in the structures of FIGS. 3 and 4, the locking mechanism 12 may further include a transmission component 125 connected transmissively between the driving component 124 and the lock lever 123. The transmission component 125 may be a worm-gear component, a gear transmission component or a threaded transmission component. As shown in the structure of FIG. 4, the transmission component 125 is a worm-gear transmission component and includes a transmission component housing 1251 within the housing 121, a worm 1252 transmissively connected to the driving component 124, and a worm gear 1253 engaged with the worm 1252. The worm gear 1253 is co-axial with and connected to the lock lever 123 by means of key joint. The driving force applied by the driving component 124 is transmitted to the lock lever 123 via the worm 1252 and the worm gear 1253, driving the lock 122 to lock and unlock the locking mechanism 12.

The above driving component 124 may be an electric motor such as a stepper motor, a Direct Current (DC) motor, a variable frequency motor, or the like.

In order to improve the alignment accuracy and locating efficiency in hoisting of the container, the above vehicle 1 may further include a plurality of guiding blocks 15 mounted to the vehicle body 11 and configured to locate the container such that the container is aligned with each of the locking mechanisms 12. As shown in the structure of FIG. 1, the plurality of guiding blocks 15 may be stop plates provided at four corners of the vehicle body 11, respectively, or may be other structures, e.g., stop blocks, provided at other positions of the vehicle body 11. With the guiding blocks 15, the container may be aligned with the locking mechanisms 12 rapidly, so as to avoid waste of time and reduced transportation efficiency of the vehicle 1 due to misalignment between the container and the locking mechanisms 12.

In order to improve the automation and utilization of the above vehicle 1, as shown in the structure of FIG. 2, the vehicle 1 may further include a distance detection unit 16 and an Electronic Control Unit (ECU) 17 each communicatively connected to the microcontroller unit 13. The ECU is also referred to as “driving computer” or “on-board computer”. The distance detection unit 16 may be an optical sensor, an infrared sensor, an ultrasonic sensor or the like.

The electronic control unit 17 is configured to automatically control the vehicle 1 to enable automated driving of the vehicle 1.

The distance detection unit 16 is configured to detect a distance between the container and the vehicle body 11 in a vertical direction and transmit a value of the detected distance to the microcontroller unit 13, such that when the value of the distance detected by the distance detection unit 16 is larger than a predetermined distance, the microcontroller unit 13 transmits a movement signal to the electronic control unit 17 and the electronic control unit 17 controls the vehicle 1 to move based on the movement signal received from the microcontroller unit 13.

When the container is offloaded from the vehicle 1, the distance detection unit 16 may detect the distance between the vehicle body 11 and the container. When the distance between the vehicle body 11 and the container is larger than the predetermined distance, the microcontroller unit 13 may determine that the container will not affect movement of the vehicle 1 and may thus transmit a signal to the electronic control unit 17 which may then control the vehicle to move. Accordingly, the cooperation of the distance detection unit 16 and the electronic control unit 17 allows automated driving of the vehicle 1, such that the vehicle 1 may be fully utilized and the transportation efficiency and utilization of the vehicle 1 may be improved.

The above vehicle may be an unmanned vehicle, an ordinary truck or rail vehicle, or an unmanned rail vehicle.
